Subjective evaluation of FM/FM protection ratio for television broadcasting by satellite / by Chun Loo ; appendices A and F contributed by G. Chouinard and W.B. Tonner. : Co24-3/7-1340-1980E-PDF
"This report describes subjective measurements of the interference between two FM TV signals at the same carrier frequency and at different carrier frequencies. The results show that there is no masking of the interference due to additive Gaussian noise in the wanted channel as reported by others. Also, the results do not support the conclusion that an impairment grade of 4.5 on the CCIR scale is subjectively equivalent to just perceptible interference. Finally, a comparison of results of measurements of the protection ratio and its variation with frequency offset with those obtained by others shows reasonably good agreement"--Abstract, page 1.
